Definitions

  • the invention relates to a tubular insulating material consisting of a composite of closed-cell foam, a film and a mesh-like protective structure.
  • Such tubular insulation materials are widely used for the insulation of metallic pipes.
  • thermoplastic foam From DE-A-26 16 537 reinforced sheets of thermoplastic foam are known, which are intended for mattresses, mattress edges, pillows for sleeping and for envelopes for mailing. These multi-layer panels can have a mesh-like structure between two layers to reinforce the composite material. An adaptation of this plate material to a body to be enclosed is not provided.
  • the object of the invention is to design a tubular insulating material of the type specified in such a way that, with negligible additional expenditure, the strength is decisively increased and the risk of uncontrolled cracking in the insulating material is completely eliminated.
  • the foam present in strip form is shaped into a tube, that a thread grid made of polyester or glass fiber is integrated into the film laminated onto the foam and enclosing the foam, and that the rectangular, parallelogram-like or diamond-shaped Individual fields of the lattice structure in the case of extreme loads in the form of impacts, squeezing processes and the like form small-area crack delimitation areas.
  • the combination of a mesh structure with the film also indirectly increases the film strength, since overstretching is largely excluded in some areas.
  • the insulating tube marked with the general reference number 1 consists of a closed-cell foam layer 2, which is laminated with a plastic film 3.
  • a lattice structure consisting of threads 4, 5 running essentially perpendicular to one another is applied to the film 3. These are preferably made of polyester fibers or fibers made of glass fibers, welded or glued to the plastic film 3, so that this lattice structure can increase the strength of the foam covering or the film surrounding the foam.
  • the threads of the lattice structure run parallel to the hose axis or perpendicular to it in the circumferential direction of the hose. This is a preferred embodiment, but does not limit the invention to this particular structure.
  • a lattice structure with essentially rectangular individual fields instead of a lattice structure with essentially rectangular individual fields, a lattice structure with parallelogram-like or diamond-shaped individual fields can also be used.

Description

  • Die Erfindung betrifft ein rohrförmiges Isoliermaterial, bestehend aus einem Verbund aus geschlossenzelligem Schaumstoff, einer Folie und einer netzartigen Schutzstruktur.
  • Derartige rohrförmige Isoliermaterialien werden im großen Umfange zum Isolieren von metallischen Rohren verwendet.
  • Da solche rohrförmigen Isoliermaterialien im rauhen Baustellenbereich erheblichen Belastungen und Beschädigungsgefahren ausgesetzt sein können und häufig auch ausgesetzt sind, kommt es immer wieder vor, daß in den Isoliermaterialien Risse und Schlitze entstehen, die auch die Isoliereigenschaften beeinträchtigen und vor allem die Tendenz haben, weiterzureißen und damit das jeweilige Isoliermaterial unbrauchbar zu machen.
  • Aus der DE-A-26 16 537 sind verstärkte Platten aus thermoplastischem Schaum bekannt, die für Matratzen, Matratzenkanten, Kissen zum Schlafen und für Umschläge für den Postversand bestimmt sind. Diese aus mehreren Schichten bestehenden Platten können zwischen zwei Schichten eine netzähnliche Struktur zur Verstärkung des Verbundmaterials aufweisen. Eine Anpassung dieses Plattenmaterials an einen zu umschließenden Körper ist dabei nicht vorgesehen.
  • Aufgabe der Erfindung ist es, ein rohrförmiges Isoliermaterial der eingangs angegebenen Art so auszubilden, daß bei vernachlässigbarem Mehraufwand die Festigkeit entscheidend erhöht und die Gefahr einer unkontrollierten Rißbildung im Isoliermaterial völlig ausgeschaltet wird.
  • Gelöst wird diese Aufgabe nach der Erfindung dadurch, daß in Streifenform vorliegender Schaumstoff zu einem Rohr geformt ist, daß in die auf den Schaumstoff aufkaschierte und den Schaumstoff umschließende Folie ein Fadengitter aus Polyester- oder Glasfaser intergriert ist, und daß die rechteckigen, parallelogrammartigen oder rautenförmigen Einzelfelder der Gitterstruktur bei extremen Belastungen in Form von Schlägen, Quetschvorgängen und dergleichen kleinflächige Rissbegrenzungsbereiche bilden.
  • Vorteilhafte Ausführungsformen der Erfindung sind in Unteransprüchen beschrieben.
  • Durch die Kombination einer Netzstruktur mit der Folie wird indirekt auch die Folienfestigkeit erhöht, da Überdehnungen in Teilbereichen weitestgehend ausgeschlossen werden.
  • Selbst unter härtesten Baustellenbedingungen und bei unvorsichtiger Handhabung dieses in Schlauchform vorliegenden Isoliermaterials sind die Beschädigungsgefahren absolut minimiert.
  • Ein Ausführungsbeispiel der Erfindung wird in Verbindung mit der Zeichnung näher erläutert; die einzige Figur der Zeichnung zeigt einen Abschnitt eines rohrförmigen Isoliermaterials nach der Erfindung.
  • Der mit dem allgemeinen Bezugszeichen 1 gekennzeichnete Isolierschlauch besteht aus einer geschlossenzelligen Schaumstoffschicht 2, die mit einer Kunststoffolie 3 kaschiert ist.
  • Auf die Folie 3 ist eine Gitterstruktur aus im wesentlichen senkrecht zueinander verlaufenden Fäden 4, 5 aufgebracht. Vorzugsweise sind diese aus Polyesterfasern oder aus Glasfasern bestehenden Fäden mit der Kunststoffolie 3 verschweißt oder verklebt, so daß diese Gitterstruktur die Festigkeit der Schaumstoffumhüllung bzw. der den Schaumstoff umschließenden Folie erhöhen kann.
  • Sollte durch extreme Belastungen, Schläge, Quetschvorgänge oder dergleichen die Gefahr von Rißbildungen in der Folie 3 auftreten, so werden die Maximalausdehnungen eines eventuellen Risses auf ein Gitterelement beschränkt, da die Gitterfäden jeglichen Effekt des ansonsten vorhandenen Weiterreißens unterbinden. Als Gitterfäden eignen sich alle Materialien von ausreichend hoher Reiß- bzw. Zugfestigkeit, die mit der Kunststoffolie auf einfache Weise dauerhaft verbunden werden können.
  • Im dargestellten Ausführungsbeispiel verlaufen die Fäden der Gitterstruktur parallel zur Schlauchachse bzw. senkrecht dazu in Umfangsrichtung des Schlauches. Dies ist ein bevorzugtes Ausführungsbeispiel, schränkt aber die Erfindung nicht auf diese spezielle Struktur ein.
  • Anstelle einer Gitterstruktur mit im wesentlichen rechteckigen Einzelfeldern kann auch eine Gitterstruktur mit parallelogrammartigen oder rautenförmigen Einzelfeldern Verwendung finden.
